Minute Repeater, Annual Calendar and Equation of Time: the new Girard-Perregaux 1966 houses three prestigious watchmaking complications in its 42 mm case.

The solid gold applique hour-markers with sharply defined profiles stand out in the elegant silvered sunburst dial. The date is displayed at 1:30 while the month is on the opposite side of the dial at 7 o'clock. The Annual Calendar only required adjustment will recur at the end of February.

The Equation of Time - at 4:30 on the dial - shows the difference between civil time and solar time. For, in reality, the solar day varies in duration from day to day. While the two reference times in question coincide exactly four times per year, the accumulated difference between them can be as much as, for example, 16 minutes in November.

Last, the Minute Repeater enables the user to hear the striking of the hours, quarter-hours and minutes. The fruit of exhaustive acoustic research, the Girard-Perregaux Minute Repeater mechanism benefits from three specially designed aspects of the construction of the watch-case: an optimal fit between the internal diameter of the case and that of the calibre, so as to achieve maximum resonance; a curved case back that increases the volume of air between the movement and the case, and enhances the sound production; and the diamond-polished bottom of the case back, which reduces acoustic interference.

Visible through the sapphire crystal case back, the manually wound mechanical calibre perpetuates the high Girard-Perregaux watchmaking tradition. With its constant concern for aesthetic standards, Girard-Perregaux has designed the balance-cock in a semi-arrow shape that remind of the Golden Bridges, the brand's emblematic signature.
